Short summary
During a flood event over a karst watershed, the karst may attenuate surface floods by absorbing water or contribute to the surface flood by direct contribution of karst waters in the rivers and by diffuse resurgence along the hillslopes. If it is possible to monitor each known outlet of a karst system, the diffuse contribution is yet difficult to assess. We present here a new, original method to do it, based on chemical analysis and a hydraulic study.
